Sun Java Enterprise System 5 Update 1 Release Notes

Java SE 5.0 Update 12 is not compatible with Application Server 7 (2137473, 6203688, 6409072)

Java ES 5 Update 1 is certified with Java SE 5.0 Update 12 (1.5.0_12). If the Java ES installer does not find this version of Java SE on a system, the installer installs this version and makes it available to Java ES components though the symbolic link /usr/jdk/entsys-j2se.

The version of Application Server 7 that shipped with Java ES 2004Q2 makes use of this symbolic link, but is not compatible with Java SE 5.0 Update 12. Thus, Application Server 7 stops functioning correctly after you install Java ES 5 Update 1 components.

Solution Java ES does not support a mixture of version 2004Q2 and version 5 Update 1 components on a single system. When upgrading a system from Java ES 2004Q2, you must upgrade all components. If you need access to Application Server 7 during the upgrade process, you can change its configuration to point to Java SE 1.4.2, which was installed with Java ES 2004Q2:

  1. Login to Sun Java System Application Server 7 administration console.

  2. Update Java settings for the admin server and every application server instance, changing Java Home to point to the Java SE 1.4.2 location. Remember to "Apply Changes" for every instance.

  3. Stop all application server instances including the admin server.

  4. Modify the asenv.conf file in the config subdirectory of Application Server 7, setting AS_JAVA to point to the Java SE 1.4.2 location.

  5. Restart Application Server 7.
